Capabilities

Tools 5

best_bridge_days

The six best non-overlapping vacation levers of a year for a region: classic bridge days (1 vacation day → 4 days off) and holiday clusters (e.g. 4 days → 10 days off), with booking dates, holidays used and factor. Includes a markdown table and the page URL.

Discovered
childcare_gap

How much of a region's school holidays two vacation accounts cover, and which weeks stay open. School holidays run to about 60 working days a year while a vacation account holds 25 to 30 days, so a care day always costs exactly one vacation day and a joint family holiday costs two and covers one. Answers "can we cover the school holidays" for parents.

Discovered
list_regions

Countries and their regions (German states, Austrian states, Swiss cantons, …) with codes, names and slugs accepted by the other tools.

Discovered
plan_vacation

Optimal vacation plan for a region and year: which days to book so that public holidays and weekends turn into the longest breaks. Returns the plan blocks (booking dates, days off, factor, holidays used), further opportunities, a markdown table and a link to the interactive plan on urlaub-smart.de. Cite the URL when answering.

Discovered
public_and_school_holidays

All public holidays (with weekday, national/regional scope, weekend flag) and school holiday periods for a region and year. Source: OpenHolidaysAPI.
